bochs-3.0 has been released recently, but Gentoo provides bochs-2.7 from 2021 - which is understandable, as there has been only 2.8 released in 2024 since then. If needed, I can provide a slightly tested bochs-3.0.ebuild + patch for man pages install that adds USE for a few new features: [ebuild U ~] app-emulation/bochs-3.0::localrepo [2.7::gentoo] USE="3dnow X amx%* avx ncurses readline sdl smp svm%* uintr%* vmx%* wxwidgets%* x86-64 -debugger -doc -gdb -sdl2% -vnc" 0 KiB but it definitely has issues with dependencies (especially wxwidgets looks complex in other ebuilds), but I can't upload it here due to not having the needed "GCO sign-off": ... 3. Patches, ebuilds and other copyrightable files meant for integration must conform to the Gentoo copyright policy. Such conformance must be explicitly acknowledged through GCO sign-off, confirmed with your real name. 4. Please attach ebuild updates and new packages preferably as git-format patches with explanatory commit messages (see: GLEP 66) and a GCO sign-off. Alternatively, please include the sign-off in a comment when attaching non-patch format files.
